Wanna really good Bluetooth mouse for cheap?

Every now and then I come across a really good deal by complete happenstance. Last week my $70 Logitech VX mouse that I’ve used for two years completely lost its mind. The cursor began freezing occasionally and left button clicks were very erratic. Sometimes I would have to click on something two or three times before anything would happen. After trying all the usual remedies to no avail, new battery, repositioning the USB dongle, etc., I went mouse shopping. I decided to look for a Bluetooth mouse to eliminate the need for a dongle. My (late 2013) MacBook Pro only has two USB ports and besides, a dongle is just one more thing to get lost in the bottom of my laptop bag. There are tons of wireless mice requiring a dongle, but after looking far and wide on the web for Bluetooth mice, I was disappointed by how limited the selection is. I was about to give in and fork over 70 bucks to Apple for a MagicMouse when I decided to take a second look at the bargain basement offerings at Amazon. The TeckNet Bluetooth mouse is one of those. For $11.97 and free shipping from Amazon Prime, I figured “what the hell?” and bought it with One-Click. Two days later the UPS man dropped it off.
